How to enable HTT under 5-CURRENT ... ?

'k, I'm lost ... checked through the NOTES kernel config, to make sure 
that I wasn't missing anything, and I don't think I am ...

My CPU comes up as supporting HTT:

CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz (2393.19-MHz 686-class CPU)
   Origin = "GenuineIntel"  Id = 0xf27  Stepping = 7

I have ACPI enabled in the BIOS ...

I tried setting cpu_idle_hlt to 0 in /etc/sysctl.conf, which I *thought* 
was what I needed to do, but it states:

Jun 10 16:20:40 ganymede root: /etc/rc.d/sysctl: WARNING: sysctl machdep.cpu_idle_hlt: does not exist.

where the following tells me that it does:

ganymede# sysctl machdep.cpu_idle_hlt
machdep.cpu_idle_hlt: 1

Attached are my dmesg.out for the machine, as well as my kernel config 
file ... am I missing a setting here somewhere?
